Information
Mtrace is an IGMP protocol based on the Multicast trace route facility and implemented according to
the IETF draft “A trace route facility for IP Multicast” (draft-fenner-traceroute-ipm-01.txt). Dell
Networking OS supports the Mtrace client and transmit functionality.
As an Mtrace client, Dell Networking OS transmits Mtrace queries, receives, parses and prints out the
details in the response packet received.
As an Mtrace transit or intermediate router, Dell Networking OS returns the response to Mtrace
queries. Upon receiving the Mtrace request, Dell Networking OS computes the RPF neighbor for the
source, fills in the request and the forwards the request to the RPF neighbor. While computing the RPF
neighbor, the static mroute and mBGP route is preferred over the unicast route.
